Long, long ago I had a battle.net account with one of the physical authenticator tokens. A year or so ago, the battery died in it. I’m trying to recover my account but can’t find a way to contact blizzard to remove the old authenticator without having it functional.
Does anyone have a link I can contact them at to remove a non-functional authenticator?

This seems to fit your issue.
